My kindletouch is one thing, doing is another 5.1update of the state
Before reinstalling Os diags mode, you have accidentally entered the reboot has become a brick
When you reboot a brick even if recovery

I use win7 64bit

mmcblk0p1-kt-5.0.0.img, mmcblk0p2-kt-5.0.0.img, mmcblk0p2_ssh-kt-5.0.1.img.gz
I got the three files

mmcblk0p1-kt-5.0.0.img, mmcblk0p2-kt-5.0.0.img
Did you meet these two?

fastboot flash diags mmcblk0p2-kt-5.0.0.img
dd if = / mnt/us/mmcblk0p1-kt-5.0.0.img of = / dev/mmcblk0p1 bs = 4
Is this way works well on the input haneunge?
Command or file name, it is advantageous to change to match the?
And
/ mnt/us/mmcblk0p2-kt-5.0.0.img file location right?

Anger selectboot using fastboot mode, but is there a way to ensure he did exactly?
Fastboot is not detected, you can enter the command
Does that need to be connected separately Kindle??
